The raw materials are all polymer materials, and the polymer materials will inevitably deteriorate in the process of synthesis, transportation, storage, processing and product finalization, and the physical performance indicators will decline, that is, aging. The manifestations of aging such as yellowing, loss of luster, cracking on the surface of the product, powdering (polypropylene), and more serious mechanical properties such as tensile strength, impact strength, folded strength and elongation at break are greatly reduced, thereby losing Use performance.
Common aging can be divided into two categories: aging and photo-oxidative aging. With the presence of temperature, along with the presence of oxygen in the air, there is aging; with the presence of light, that is, ultraviolet radiation, accompanied by re-airing in the air, there is photo-oxidative aging, it is precisely the plastic woven raw materials produced from the factory, During the whole process of storage and transportation, processing and molding, and use, it is also exposed to heat and oxygen in the environment and sunlight (ultraviolet rays).
Plastic weaving enterprises should note that the pellets of plastic weaving polypropylene raw materials have been added with a teaming agent in the production process. The resin manufacturer ensures that no major aging will occur during production, storage and transportation. However, the powder does not add anti-aging agent, and the plastic weaving enterprise should not store it for too long, because the surface layer of the powder will age seriously with the storage time. , The polyethylene raw materials used in plastic weaving generally do not need to consider storage and transportation aging.
